For each flavor, place 3 scoops of the chosen ice cream and 1/3 cup of whole milk into a blender. If making a strawberry milkshake, add the chopped strawberries.
Blend each one on high speed until the mixture is smooth and creamy.
Pour the milkshakes into glasses and, if desired, top with whipped cream or other toppings, like sprinkles or a cherry.
